Hi Guys, I have found the issue. I did not exit Hive using quit; but instead using the Ctrl Z. As a result, background processed for Hive were running and causing trouble in the query execution.
I killed the running Hive processes and was able to run Hive with derby as well as MySQL as metastore DB. Thanks!

The error is as follows which occurs while running any query in Hive from the terminal FAILED: Error in metadata: javax.jdo.JDOFatalInternalException: Error creating transactional connection factory NestedThrowables: java.lang.reflect.InvocationTargetException FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask I installed CDH3U2 Hadoop and Hive version and the only changes I have made in Hive configuration are as follows: 1. export HIVE_AUX_JARS_PATH=/usr/local/hadoop 2. There is no Hive-site.xml so i made changes in the hive-default.xml as follows: <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:postgresql://localhost:5432/hadoop</value> <description>JDBC connect string for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>org.postgresql.Driver</value> <description>Driver class name for a JDBC metastore</description> </property> <property> <name>javax.jdo.PersistenceManagerFactoryClass</name> <value>org.datanucleus.jdo.JDOPersistenceManagerFactory</value> <description>class implementing the jdo persistence</description> </property> <property> <name>javax.jdo.option.DetachAllOnCommit</name> <value>true</value> <description>detaches all objects from session so that they can be used after transaction is committed</description> </property> <property> <name>javax.jdo.option.NonTransactionalRead</name> <value>true</value> <description>reads outside of transactions</description> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hadoop</value> <description>username to use against metastore database</description> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>hadoop</value> <description>password to use against metastore database</description> </property> 3. I have placed postgresql-9.1-901.jdbc4.jar in the /usr/local/hadoop path 4. Installed Postgresql and created username/pass hadoop/hadoop 5. postgresql.conf - uncommented the listen_addresses = 'localhost','*' while adding the '*' part to it. Please help me understand why this error would be occuring. Thanks in advance!
